Dear Maintainer,
your package depends on libeigen3-dev. The upstream released a
new major version of this mathematical library, 5.0.0. Some
basic information about new features and changes in this version
can be found here:
https://libeigen.gitlab.io/releases/5.0/
This is a major version change and may require code changes in packages
depending on eigen3. The key breaking changes include:
- Minimum required C++ standard is now C++14
- Changes in the build system integration
- Some API name changes
lbfgspp FTBFS with libeigen3-dev 5.0.1. The full build log is available at:
https://debusine.debian.net/debian/developers-gladk-eigen3/artifact/3757053/
Here is the most probably relevant part of the failing build log:
===========================================
- -- Performing Test WALL_SUPPORTED
- -- Performing Test WALL_SUPPORTED - Success
CMake Error at CMakeLists.txt:41 (find_package):
Could not find a configuration file for package "Eigen3" that is compatible
with requested version "3.0".
The following configuration files were considered but not accepted:
/usr/share/eigen3/cmake/Eigen3Config.cmake, version: 5.0.1
The version found is not compatible with the version requested.
- -- Configuring incomplete, errors occurred!
cd obj-x86_64-linux-gnu && tail -v -n \+0 CMakeCache.txt
===========================================
libeigen3-dev_5.0.1-1 is available in experimental.
When this package version lands into unstable (probably at the beginning
of June 2026), this bug will be increased in severity to serious.
Thanks,
Anton
